Introduction.
In order to reduce the large variations in clinical outcomes of patients with implanted MED-EL Floating Mass Transducer (FMT) at the round window (RW), several approaches were proposed to optimize FMT-RW coupling.
Our previous study showed improved FMT-RW coupling by applying static RW loads utilizing the “Hannover Coupler” (HC) FMT-prosthesis but also demonstrated insufficient low frequency performance.
Hence, a redesigned HC version (HCv2) was investigated in this study.
Methods.
Experiments were performed in ASTM F2504-05 compliant fresh human temporal bones.
The HCv2 is a FMT-prosthesis redesigned from a previous prototype to specifically improve low frequency performance.
Stapes footplate (SFP) displacements in response to acoustic stimulation of the tympanic membrane and to FMT-RW stimulation at varying static force (0–100 mN) were measured by Laser-Doppler vibrometry.
Results.
SFP displacements were highly dependent on the applied RW load and had a global maximum at 15 mN when averaged at speech relevant frequencies (0.5–4 kHz).
SFP responses at frequencies ≤ 1 kHz were up to 25 dB higher than responses achieved with the previous HC version.
Conclusion.
Optimizing the HC prosthesis design resulted in improved SFP responses to RW stimulation especially at lower frequencies (≤1 kHz).
